Save on a high-efficiency heat pump and furnace combination

Dual fuel technology combines the efficient heating and cooling performance that you get from a heat pump with the consistent heating capacity of a gas furnace. In summer, the heat pump works like a high-efficiency central air conditioner. In spring, fall and winter it provides cost-effective and efficient heating, while the gas furnace takes over only when needed during the coldest months of the year.
